I sometimes get this odd condition where my fingers itch and swell, although the swelling isn’t that noticable. It’s not a skin condition; there’s no redness or anything. I can’t pin down what causes it, though. I’ve had it as long as I can remember, but only every now and then, and it goes away after an hour or so.
I sometimes get this in the middle of the night, then have to sit around posting here, until the antihistamine kicks in, stops the itch, and I can go back to sleep.
When my fingers swell, it’s almost always because I’ve had too much salt. The itching could be just a reaction of the skin to being stretched by the swelling.
IANAD, but the fact that it’s only happening in your hands indicates that it could be contact dermatitis due to allergy. Is there anything you come in regular contact with that could cause this? Latex gloves, certain chemicals, pets, etc.?
Maybe QtM might come along and be able to offer some insight on this…
